A powder paint spray gun, also known as an electrostatic spray gun, is a specialized tool used to apply powder paint to various surfaces. Unlike conventional paint spray guns that use a liquid coating, powder paint spray guns use finely ground powder particles that are electrostatically charged to adhere to the object being coated.
Powder paint spray guns offer several advantages over traditional liquid paint spray guns:
- Durability: Powder coatings are extremely durable and resistant to chipping, scratching, and UV radiation.
- Corrosion resistance: Powder coatings provide excellent corrosion protection for metal surfaces.
- Environmentally friendly: Powder coating doesn’t require solvents or hazardous chemicals, making it a more environmentally friendly option than liquid paint.
- Thicker and smoother finish: Powder coatings typically produce a thicker and smoother finish than liquid paint.
- Less overspray: Powder coatings have minimal overspray, resulting in less waste and a cleaner workspace.
Powder paint spray guns are used in a wide range of applications, including:
- Automotive: Powder coating is commonly used for automotive parts, such as bumpers, fenders, and grilles.
- Construction: Powder coating is often used for coating metal building components, such as doors, windows, and railings.
- Industrial: Powder coating is used for a variety of industrial applications, including coating pipes, machinery, and equipment.
- Home décor: Powder coating is becoming increasingly popular for home décor items, such as furniture, appliances, and hardware.
To use a powder paint spray gun, the powder paint is first applied to the surface using an electrostatically charged air stream. The electrostatic charge attracts the powder particles to the object, forming a uniform and adherent coating. The coated object is then baked in an oven to melt the powder particles and fuse them into a solid, durable finish.
Powder paint spray guns are typically more expensive than traditional liquid paint spray guns, but they offer a number of benefits that can justify the higher cost. The durability, corrosion resistance, environmental friendliness, and smoother finish of powder coatings make them a preferred choice for many applications.
Powder Paint Spray Gun
A powder coating gun is a crucial component of the powder coating process, responsible for applying fine, charged powder particles to a workpiece surface. These guns utilize electrostatic or mechanical principles to atomize the powder and attract it to the grounded workpiece, ensuring uniform and consistent coating coverage.
Types of Powder Coating Guns
- Electrostatic Powder Coating Guns: These guns impart a charge to the powder particles, creating an electrostatic attraction between the particles and the grounded workpiece. This electrostatic force enhances powder adhesion and promotes uniform distribution, minimizing overspray and waste.
- Mechanical Powder Coating Guns: These guns rely on air pressure to atomize and propel the powder particles towards the workpiece. Mechanical guns typically offer higher powder feed rates and can handle a wider range of powder types, but they may produce more overspray compared to electrostatic guns.
Key Components of Powder Coating Guns
- Powder Hopper: The powder hopper stores the powder supply and feeds it to the powder injector.
- Powder Injector: The powder injector regulates the flow of powder from the hopper to the atomizer.
- Atomizer: The atomizer breaks down the powder particles into a fine mist, creating a spray of charged or air-propelled powder.
- Nozzle: The nozzle directs the powder mist towards the workpiece surface.
- Charging Unit (Electrostatic Guns Only): The charging unit imparts an electrostatic charge to the powder particles, typically using a high-voltage transformer.
- Air Supply (Mechanical Guns Only): The air supply provides compressed air to the atomizer for powder atomization.

We manufacture and sell powder paint spray gun models in 2 types
Manual Powder Paint Spray Gun
A manual powder paint spray gun is a type of powder coating gun that is operated by hand. It is a relatively simple and inexpensive tool, making it a popular choice for small jobs and hobbyists.
Manual powder paint spray guns typically consist of a powder cup, a fluidized bed, a spray gun, and a power supply. The powder cup is filled with powder paint, and the fluidized bed agitates the powder to create a cloud of charged particles. The spray gun then directs the charged powder particles towards the object being coated.
To use a manual powder paint spray gun, follow these steps:
- Prepare the surface to be coated by cleaning and sanding it.
- Ground the object to be coated to prevent static electricity from interfering with the coating process.
- Fill the powder cup with powder paint.
- Adjust the settings on the spray gun, such as the voltage and flow rate, to achieve the desired coating thickness.
- Spray the powder paint onto the object in a smooth, even motion.
- Bake the coated object in an oven to melt the powder particles and fuse them into a solid finish.
Manual powder paint spray guns are a versatile and effective tool for applying powder coatings to a variety of surfaces. They are relatively easy to use and maintain, making them a good choice for both beginners and experienced powder coaters.
Here are some of the advantages of using a manual powder paint spray gun:
- Affordable: Manual powder paint spray guns are typically less expensive than automatic powder coating systems.
- Portable: Manual powder paint spray guns are lightweight and portable, making them easy to use in a variety of locations.
- Easy to use: Manual powder paint spray guns are relatively easy to operate, even for beginners.

Overall, manual powder paint spray guns are a good choice for small jobs and hobbyists. They are affordable, portable, easy to use, and versatile. However, they are slower and produce more overspray than automatic powder coating systems.
The manual powder paint spray gun has 3 main parts:
- The control unit where the operator regulates the air volume, cascade voltage, and circuit
- The spray gun to apply the powder paint on the metal surface
- The injector where the venturi tube regulates the suction pressure
On the control unit of our powder coating spray gun, we have the following mechanical controllers:
- Air feeding to the injector
- Air dosing for the gun
- Vortex
These are used to control the air coming to the powder coating equipment.
There are also digital controllers for the following:
- Applying Voltage
- Applying Circuit
Powder paint guns can be either Corona-type or Tribo-type. The coroan-type powder spray gun has a cascade that increases the voltage from a 10 V incoming voltage to a 10.000 V that causes the powder coming through to have electrostatic characteristics. The Tribo-type powder coat paint gun has no electrical elements that make the powder to be electrostatic. This is done by static friction.
Powder Coat Paint Gun
The powder paint sprayer is used to apply powder coating powder onto the metal surface. There are 2 types of spray guns: An airless powder coating gun and a powder coating gun working with pressurized air.
The powder coating gun is connected to the powder coating spray machine by 2 connections: The air hose and the control cable. The spray gun for powder coating is triggered by a trigger and when the operator presses the trigger the powder coating injector send the powder with the pressurized air.
A powder coat paint gun is a specialized tool used to apply powder paint to various surfaces. Powder paint is a dry, finely ground powder that is electrostatically charged and sprayed onto the object being coated. The powder particles are attracted to the object and adhere to it.

If you are new to powder coating, it is a good idea to start with a manual powder coat paint gun. Manual guns are relatively inexpensive and easy to use. Once you have gained some experience, you can upgrade to an automatic or electrostatic powder coat paint gun.
Powder Coating Injector
The injector is used to convey normal organic powders between the powder hopper and the powder gun. The injector is supplied with a Teflon insert sleeve as standard. If air flows through the nozzle into the cavity, a vacuum is created in the cavity. This vacuum causes the powder to be drawn up the suction tube and into the cavity. A powder/air mixture is created.
The forward air velocity at the nozzle conveys the powder/air mixture through to the powder hose to the gun. The concentration of the powder/air mixture, and with it, the powder output depends on the conveying air pressure and supplementary air pressure, the quality of the powder, the length of the powder hose, the diameter of the powder hose, and the difference in the height between the gun and injector, and the type of nozzle. The condition of the insert sleeve is of great importance because wear causes the powder output to sink drastically.
- Remove the injector from the hopper.
- Pull the powder hose off the hose fitting.
- Clean the hose fitting with compressed air which is free of water and oil.
- Clean injector body with compressed air which is free of water and oil.
- Reassemble the injector and fit it on the hopper.
When the operator presses on the trigger, the injector on the hopper of the powder coating device sends the powder with air. This air-powder mix goes through the hose to the electrostatic powder spray gun and onto the parts surface. The advised distance between the powder coating system paint gun and the part’s surface is about 30 cm.
